A separation ring is disposed between the middle and the rear sections of the barrel. The piston tube is accommodated in the middle section of the barrel. The push rod is disposed in the rear section of the barrel. A plunger is provided at the front end of the push rod. The rear section of the push rod passes through the separation ring and is disposed with a piston block. An air storage space is formed between the plunger and the separation ring.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to a two-stage percussion for a paint ball gun, and more particularly, to one has a separation ring disposed between middle and rear sections of a barrel and contains a piston tube and a push rod for the latter to push the former so as to push a paint ball and increase an air storage space.

(b) Description of the Prior Art

The percussion device of a conventional paint ball gun is related to one-stage of single piece, that is, the percussion device is directly driven by the pressurized air to hold against and advance the paint ball, and the paint ball is fired once the pressurized air builds up to a sufficient amount.

The percussion device of the prior art may appear to accomplish its purpose at one go. In fact, however, when the air is discharged after the percussion, the barrel must be refilled with the pressurized air from zero before executing the next percussion. Therefore, it takes longer intermission between shots and wastes too much pressurized air.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide a two-stage percussion device for a paint ball gun by having a push rod to push a piston tube so as to push a paint ball and to increase the capacity of an air storage space.

To achieve the purpose, the present invention comprises a piston tube and a push rod in conjunction with a barrel. The barrel is hollow and comprises front, middle, and rear sections. A separation ring is disposed between the middle and the rear sections of the barrel. The piston tube is a hollow tube and accommodated in the middle section of the barrel. The push rod accommodated in the rear section of the barrel has at a front end disposed with a plunger to relatively block the rear end of the piston tube. The rear section of the push rod passes through the separation ring of the barrel, and is disposed with a piston block for the push rod to slide in the rear section of the barrel. An air storage space is formed inside the barrel between the plunger and the separation ring.

A ball drop hole and a recuperation air hole are further disposed in the middle section of the barrel. A percussion air inlet is provided in front of the separation ring of the barrel. An air inlet to push in the paint ball is disposed in the rear section of the barrel. An air discharge hole is provided in the rear end of the barrel.

In operation by the two-stage percussion device of the present invention, the air enters from the air inlet for pushing the paint ball in the barrel into the rear section of the barrel to push the piston block of the push rod. Meanwhile, the air also enters from the percussion air inlet into the air storage space of the barrel for the push rod to push the piston tube to slide in the barrel and further to push the paint ball and increase the capacity of the air storage space. Once the pressure and capacity of the air mount up to become sufficient to fire the paint ball, the air enters from the recuperation air hole into the middle section of the barrel to return the piston tube to its original position while the waste gas is released form the air discharge hole.

Accordingly, the present invention provides the following advantages:

-   -   (1) The air storage space formed between the separation ring of         the barrel and the plunger of the push rod is for the         reservation of pressurized air.     -   (2) The percussion intermission is shortened due to the air         storage space, meaning, the frequency of percussion per unit of         time is increased to make the game even more interesting.     -   (3) The present invention allows the saving of the consumption         of pressurized air.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 for a schematic view of the present invention applied in a paint ball gun, a preferred embodiment of the present invention comprises a piston tube (1) and a push rod (2) operating in conjunction with a barrel (3). The paint ball gun further includes a gun body (A), an electromagnetic valve (B), a pressurized steel cylinder (C) and paint balls (D).

The barrel (3) is a hollow tube comprising front, middle, and rear sections. A ball drop hole (31) and a recuperation air hole (35) are disposed in the middle section of the barrel (3). A separation ring (36) is disposed between the middle and the rear sections of the barrel (3). The barrel (3) is provided with a percussion air inlet (34) in front of the separation ring (36). An air inlet (33) for pushing in the paint ball is disposed at the rear section of the barrel (3). An air discharge hole (32) is disposed at the rear end of the barrel (3).

The piston tube (1) is a hollow tube accommodated in the middle section of the barrel (3) with the front end of the piston tube (1) holding against the paint ball (D). The piston tube (1) is allowed to slide between the middle section and the front section of the barrel (3).

The push rod (2) is accommodated in the rear section of the barrel (3). The push rod (2) is provided with a plunger (22) at the front end to relatively block the rear end of the piston tube (1). The rear section of the push rod (2) passes through the separation ring (36) of the barrel (3), and is provided with a piston block (21) for the push rod (2) to slide in the rear section of the barrel (3). Meanwhile, an air storage space (4) is formed inside the barrel (3) between the plunger (22) and the separation ring (36).

Accordingly, as illustrated in FIG. 2, the air enters form the air inlet (33) into the rear section of the barrel (3) to push the piston block (21) of the push rod (2). Meanwhile, the air also enters from the percussion air inlet (34) of the barrel (3) into the air storage space (4) of the barrel (3) with the plunger (22) of the push rod (2) pushing the piston tube (1) to slide in the barrel (3) and further to push the paint ball (D) and increase the capacity of the air storage space (4). As illustrated in FIG. 3, when the air pressure and its capacity increase up to an extent to strike the paint ball (D), the air enters from the recuperation air hole (35) into the middle section of the barrel (3) to return the piston tube (1) to its original position while the waste gas is released from the air discharge hole (32).
